In honor of Pi Day 2013 (3.14.2013), I am re-posting my pi calculator worksheet.
As useless as you might think this is, note that it shows methods for adding, subtracting, multiplying, and dividing numbers to a very large precision.
Be sure to turn on the "Debugger Tool" to see it slowly grind away at the solution to whatever precision you enter at the beginning of the worksheet. Hit Ctrl-F9 to start the fun!
And stay up until 1:59:26.5 AM just to show your true geekiness in all its glory.
